Pleuroxus scopuliferus Ekman, 1900

Pleuroxus scopuliferus Ekman 1900, p 78 –82, Plate 4: Figures 25–29; Frey 1993, p 163 –171, Figures 69–99.

Lectotype (selected here): a single parthenogenetic female, length 0.70 mm, with two eggs found in the sample SMNH Cladocera 34 (4068), was re-deposited as the lectotype of this taxon, in a separate tube SMNH 5846 . Label of the lectotype: ‘‘ Pleuroxus scopuliferus Ekman, 1900 , 1 ad. ♀ from Morro Chico, S Patagonia, Chile, LECTOTYPE’’.

Type locality

Unknown water body near Morro Chico, km 146 of the highway 9, Punta Arenas–Puerto Natales, southern Chile (approximately 52 ° 059200S, 71 ° 229270W).

Comments

Frey (1993) said that he did not find any of Ekman’s material of this species, and selected a neotype from a pond in Parque National de los Torres del Paine (also in southern Chile), deposited in the Zoological Museum at Uppsala University, Sweden under number UU 21290a. According to Ekman (1900), he had many specimens (including males), but they were apparently lost, or at least are absent now from his collection in SMNH, as well as in Uppsala. However, we found a single female apparently seen by Sven Ekman, and fully agreeing with the species description. So, this female may be considered as a part of the type series, and it is designated here as lectotype of P. scopuliferus Ekman, 1900 . The neotype ZMU 21290a earlier selected by Frey (1993) must be rejected ( ICZN 2000), and the type locality of this species is Morro Chico.
